Studies now reveal that the milky way which is the home to our solar system is likely to clash with Andromeda(one of the constellations situated in the northern hemisphere).
Even though Andromeda is still 2.5 million light years away, it is heading towards the our galaxy at 250 000miles per hour and it has been confirmed.
Numerous videos are available showing the animations of how the whole thing will go down but take a look at this specific video (http://www.space.com/15946-galaxy-smash-milky-andromeda-collision-video.html) hosted at space.com site.
